CN Tower, Canada

A bolt of lightning strikes the CN Tower, once the tallest free-standing building in the world, in Toronto, Canada. Tall buildings are usually equipped with lightning rods to give the electricity from a lightning strike, up to one billion volts, a safe path to the ground.

Bolts of lightning descend like tentacles from a storm-roiled sky. Benjamin Franklin discovered in 1752 that lightning is actually electricity. In his now-famous experiment, he sent a kite with a metal key tied to the string up into a thunderstorm. Sparks leaping from the key confirmed his hunch about lightning.

Lightning flashes within a cloud near Tyler, Texas. Cloud-to-cloud lightning is one of the most common types; it travels between positive- and negative-charged areas of clouds.

Bolts of lightning flash in the night during a thunderstorm in Groton, Connecticut. The myth that lightning doesn't strike the same place twice is just that—a myth. If enough charge remains after an initial lightning strike, another bolt can follow the same path, causing the flickering effect seen in some lightning strikes.

Volcanic lightning is rare, and lightning between thunderstorms and ash clouds even more so. In this photo, taken in May 2009, lightning flashes between a thunderstorm and the eruption plume from Rabaul volcano on New Britain Island in Papua New Guinea.

Mother Nature paints an electric-blue sky with a bold twist of lightning. Lightning and thunder occur simultaneously, but because light travels faster than sound, we see lightning first. Count the seconds between a flash of lightning and a clap of thunder and divide by five to estimate how far away in miles the storm is. Divide by three for kilometers.

White lightning strikes between two buildings in New York City. Lightning often strikes a high point in a given area, whether it is a tall building or a person, but not necessarily the tallest thing around, as shown in this photo.

Whips of lightning crack the sky near rural Walton, Nebraska. Because a flash of lightning is actually multiple strokes that occur in a fraction of a second, time exposure photographs like this best capture these rapid-fire displays.

Lightning streaks across the sky over Vinales Valley, Cuba. Lightning can travel up to 93,000 miles (150,000 kilometers) per second and reach temperatures of 54,000 degrees Fahrenheit (30,000 degrees Celsius), more than four times hotter than the surface of the sun.
